## What it does

zerno-lite gives an agent access to a project brief, stored context and session events, task lists, and individual task details. It can also change task fields, submit triage suggestions for human approval, and create a review task from an agent report.

The hosted server uses HTTP, and each call requires OAuth authorization. Set `project_slug` to identify the project for a user-scoped token. A ZERNO account and access to the project are required; without them, the agent cannot retrieve project context. There is no local stdio mode, and the server provides neither MCP resources nor prompts.

## Requirements
- Remote server: `https://zerno.one/mcp`

    }
}
```

### Gemini CLI

**Platform CLI: remote server**

gemini mcp add -t http zerno-lite https://zerno.one/mcp
```

## When to use it
- retrieve a project brief before starting work
- filter the backlog and inspect a task
- change a task field or status
- turn an agent report into a review task
- append a session summary to project memory

## Example prompts
- Read the brief for project `zerno-one` and tell me the next action and what to avoid.
- Find tasks in `zerno-one` using this filter, then show the details of the selected task.
- Add a short summary of this session to the memory for `zerno-one`.
